Newcomers Police Recreation Club, in a stunning reversal of early-season form, pulled off a major upset by defeating defending Commercial Cricket League champions St. David's - Cup Match star Lionel Cann included - by two wickets at Lord's.

But the weekend was marred by a fresh round of hostilities between North Village and Jamaican Association which ended with Village 43 runs short of victory when the Jamaicans stormed off the pitch at Shelly Bay in disgust over two umpiring decisions that went against them and handed the points to their rivals.

Elsewhere, Leg Trappers maintained their two-point advantage over Village with an emphatic nine-wicket win over Devonshire Stars while West Indian Association edged Forties by two wickets in the other fixture.

Police's return after two earlier stints in the league was marked by a four-wicket defeat against Village and a nine- wicket loss to Forties and even though St. David's have shown only glimpses of the dazzling cricket that brought them the league and knockout titles in 2001, another defeat appeared on the cards at Lord's on Sunday.

But a six-wicket haul by medium pacer Raj Goonewardene and a half century from opener David Fray, coupled with a belligerent unbeaten 28 from number 10 Ian (Sumo) Simpson, helped Police turn the form-book upside down and pull off victory over 10-man St. David's.

"We're pleased to get our first victory," said Police skipper Jim Walters. "We've obviously got a little more depth than we thought."

The presence of Cann, whose return to first-team action has been held up by a nagging groin injury, seemed certain to guarantee St. David's their first victory of the season but he made only 19 in his team's 169 and although he took two wickets, his 10 overs went for 55.

George Cannonier was top scorer with seven fours and two sixes in his 61 and Kenny O'Connor made 23 as Goonewardene claimed six for 65 from 13 overs and Paul Roberts chipped in with three for 18.

Fray, a teacher, struck eight fours and a six in his 51 while Goonewardene followed up six wickets by making 25 but Police were still well short of their target until "Sumo" Simpson came in to wrestle the initiative back from St. David's by blasting 4,4,2,4,4,4,6 - 18 runs coming off the final over from Dale Lamb (two for 27) - as the visitors eased home to 175-8 from 34 overs, their total boosted by 32 extras.

Jamaican Association matches against North Village have often been marked by acrimony in the past and Sunday's fixture ended abruptly as the Jamaicans ignored appeals from their manager Glenmore Barrett and his Village counterpart Wendell Lindsay to complete the game.

The Jamaicans were angered when an appeal for a legside catch against in-form opener Robin Swan (19) was turned down and they later walked off - with Village 96 for three in 25.1 overs in reply to the Jamaicans' 138 - immediately after an appeal for a stumping against Kenny Thompson (36 not out) was also turned down.

"It looked like it might turn ugly out there and the boys decided if Village wanted the points so badly they could have them. They decided to walk off. It didn't make sense to carry on playing," said Barrett.

"We play fair and fairness is what we are looking for. Right now, our boys are very discouraged."

Presley Millwood (35) and Junior Lindo (25) were top scorers for the Jamaicans while the pick of the Village attack were Chris Caisey (four for 43) and Thompson (three for 16).

Jamaican Association, skippered by Lloyd Morrison, have struggled after losing key players David Gibbs, who has returned to Somerset, Simroy Crosdale, currently sidelined with a serious shoulder injury, and former captain Ian Coke whose church duties have ruled him out of playing on Sundays.

Devonshire Stars' skipper Derek Smith continued to lead from the front, smashing five sixes and two fours in an unbeaten 57 as his team made 109 against Leg Trappers at Garrison Field, Colin Scaife taking four for 22 from 10.2 overs and Jonathan Hughes two for 20.

Although Gary Knight went for two, David Hosier and Andy Trinder (38 not out) saw Trappers home in 24 overs, Hosier's unbeaten 53 including three fours and two sixes.

Forties suffered their first defeat of the season - a "heart-breaking" loss, according to skipper Gordon Campbell - as West Indian Association, led by a half century from skipper Barry Richards, took advantage of a hatful of dropped catches to reach their target in the 38th over at the Royal Naval Field.

Their task was made easier by a scorebook discrepancy which saw Forties' original total of 151 for six reduced to 141 for six, highlighted by Allan Lee's 36, Campbell's 31 and 23 from Mark Melvin with pacers Junior Watts, Stan Francis and Jerry Callender sharing the wickets.

Opener Richards' 54 in WIA's 144 for eight included nine fours and a six but he admitted: "I was dropped about five times."

There were three wickets apiece for Campbell and Lee while Brian Holdipp took two for 25.
